Claims. (Cl. 155-179) This invention relates in general to supportingmembers for springs of spring constructions, and, more particularly tosupporting rails for sinuously corrugated wire springs assembled to wirespring constructions.

The primary object of this invention is the provision of a rail memberadapted to readily removably and non-shiftably support corrugated wiresprings of the type embodying left and righthanded loops connected witheach other by cross wires. the rail member including for each spring tobe supported two aligned, hook-shaped elements arranged in laterallyspaced, reversed relation with respect to each other to seat and gripopposite sides of one of the cross wires oi a corrugated wire springwhen such cross wire is shifted into engagement with said elements, anda third hook-shaped element positioned in spaced, symmetrical relationwith respect to said two elements and constructed to engage and grip oneof the cross wires adjacent to the cross wire seated and gripped by thesaid two aligned hook-shaped elements.

Another object of the invention is the provision of a rail memberadapted to readily removably and non-shiftably support sinuouslycorrugated wire springs embodying left and right-handed loops connectedwith each other by cross wires, the rail member including, for eachspring to be supported, two, aligned, struckup portions havinghook-shaped form and arranged in laterally spaced, reversed relationwith respect to each other to effect seating and gripping of oppositesides of one of the cross wires of a corrugated wire spring, when suchcross wire is shifted into engagement with said elements, and a thirdhook-shaped struck-up portion having hook-shaped form and arranged inspaced symmetrical relation with respect to said two struck-up portions,said third struck-up portion adapted to engage and grip one of the crosswires adjacent to the cross wire seated and gripped by the said twostruck-up portions.

a further object of the invention is the provision of a rail member asdescribed above in which the two aligned, hook-shaped, struck-upportions which are arranged in laterally spaced,

, reversed relation with respect to each other iiielude opposed, slantededge portions to facilitate locking engagement of a corrugated wirespring with the hook-shaped. struck-up portions by retating the springwhile one of its cross members is positioned between the two struck-upportions.

in view, the invention has other marked improvements and superioritieswhich radically distinguish same from presently known structures. Theseimprovements and superior characteristics. embodying certain novelfeatures oi construction are clearly set forth in the appended claimsand the preferred embodiment oi the invention hereinafter shownwith-reference to the accompanying drawing forming part of thespecification.

In the drawing:

Fig. i is a plan view oi a rail member constructed in accordance withthe invention, the rail member having attached thereto singleconvolutions oi sinuously corrugated wire springs;

Fig. 2 is a sectional view on line 2-2 of Fig. 1;

Fig. 3 is a plan view oi a rail member similar to Fig. l having placedthereon a i 'ragmentarily shown corrugated wire spring in position toengage when rotated a cross wire with the two cbgoperating struck-upportions of the rail mem- Fig. 4 is a plan view similar to Fig. 3showing in i'uli line the corrugated wire spring properly mounted on therail member and in dash-dotted lines the wire spring just before itsengagement with the third struck-up portion oi the rail member;

Fig. 6 is a sectional view on line 8-t oi Fig. 1.

Referring now more in detail to the exemplified form oi the inventionshown in the drawing, reference numeral 2 denotes a ill-shaped raiimember 1: M i a seating or resting portion 3 having downwardly extendedside flanges t and t. Seating or resting portion 8 is termed with aplurality of groups oi hoot. members, each group oi which includes twoaligned, hookshaped elements 8 and l laterally spaced irom each other ashort distance and reversed with respect to each other to extend theiropen ends in opposite directions, and a third hook-shaped element tpositioned in spaced, symmetrical relation with respect to elements 8and l. These latter elements are struck up irom seating portion I whichfor such purpose is slit to form oppositely extending tongue members 8and i0- tongue member 6 being bent upwardly and outwardly andtonguemember it being bent upwardly and inwardly.

Hook-shaped elements I and I include upper wall portions Ii and il,respectively, spaced from the seating surface It of seating portion withthe above and other incidental objects a I a distance approximatelyequal to the gage amps:

. v v of the sinuously corrugated wire spring ll having its cross wireII engaged and held by elements and I.

Hook-shaped element I is positioned in spaced. symmetrical relation withrespect to hook-shaped elements' I and I and also struck up from seatingportion ,8 which for this purpose is slit to form a tongue member llbent upwardly at an angle of substantially 46 degrees and provides aseat II adapted to engage the middle portion II of cross wire IIadjoining the cross member II oi ripped convolution II of sinuouslycorrugated wire spring II.

The described hook-shaped elements cooperate as a group in properlyremovabl'y seating, holding and sripping a sinuously corrugated wirespring on rail member 2 and permit quick and eiiicient mounting anddemounting of such spring. The steps to be taken in mounting spring IIon rail member 2 are clearly disclosed in Figs. 3 and 4-and these steps,taken in reverse, enect quick and eiiicient demounting of the spring.

Mounting of a sinuoualy corrugated wire spring II on rail member 2 iseiiected by pla in the spring, as shown in Fig. 3, on the seatingsurface 14 of seating portion I so, that cross wire II extends betweenhook-shaped elements I and I, then spring II is rotated in a directionindicated by arrow 22 to engage and rip cross" wire II by wall portionsH and I! of elements I and I and seating surface 14 of seating orresting portion I (see the position or cross wire II in Pig. 4); finallycross wire II is forced into engagement with tongue member I! byyieldingly bending spring II (see dash-dotted line II) in a directionindicated by arrow 24 to shift said cross wire over tongue member l1 anddownwardly and then by releasing spring II cross wire II isautomatically engaged with hook-shaped element I when the spring,allowed to snap back, regains its original shape.

Preferably, as shown, hook-shaped elements I and I have opposing corneredges of their upper wall portions II and II cut on slan nsparal. lellines 2i and II, respectively. to facilitate locking engagement of theseelements with' the cross member of a sinuously corrugated w'ire springplaced on seating portion I so that one of the cross wires or the wirespring is positioned between the hook-shaped elements I and Rail membersof the type ducribed are particularly well suited for sinuouslycorrugated wire springs made of wire with gauges ran in from 10 to 14,which wires can readily be handled in the manner described without useof special tools and danger of deformation.
